解决方案

1。在控件中有一个公共属性，它将获取参数（可能包含在结构中）

2.在此属性的集合中执行所有绑定并将数据表保存在某个缓存中。

3.有另一个公共财产，其中get将返回此数据表。

< blockquote>如果你在aspx页面中有这样的控制：



< uc1：PrintProposalFees ID =PrintProposalFees1runat =server/>





传递代码后面的值，如下所示：

 this.PrintProposalFees1.ProposalID =3或你的价值; 
 

请记住控制ID不是控件！





并且在你的控制中放置这个属性：

 命名空间 UHSRFP.Features.UI 
 {
  public   partial   class  PrintProposalFees：UserControl 
 {
  private   int  myproposalID = -1; 
 
  public   int  ProposalID 
 {
  get  { return  myproposalID; } 
  set  {myproposalID =  value ; } 
}

解决方案

1. Have a public property inside the control that will take the parameters (possibly wrapped inside a struct)
2. in the set of this property do all the binding and save the datatable in some cache.
3. have another public property the get of which will return this datatable.

This may help you. Check once

if you have such control in your aspx page :

<uc1:PrintProposalFees ID="PrintProposalFees1" runat="server" />


pass the values from code behind like this :

this.PrintProposalFees1.ProposalID= "3 or your value";

remeber to call the controll ID not the control!


AND in your control put this property:

namespace UHSRFP.Features.UI
{
    public partial class PrintProposalFees : UserControl
    {
       private int myproposalID = -1;

       public int ProposalID
       {
           get { return myproposalID ; }
           set { myproposalID = value; }
       }

thats all
